Sure, having the US DoD establish an international taskforce to hunt and subdue Mitsuha, the Bezos Family plans to assassinate her, and her lesbian harem is in open revolt against her. Saving 80k gold is NOT a power fantasy because Mitsuha's actions absolutely are coming to bite her in the ass and if you cant see that from the first fracture in the Harem during the road trip where Sabine and Colette begin The War for the Loli you have no idea just what the story is really about.

They also know theyre not being subtle right, like thats clearly Archangel Kaoru from the Book of The Angel doing Kaoru the Angel things."
Average Abilities is the only one of 3 that fits a power fantasy and thats because the MC is literally cursed with divinity, and a major conflict is the gap between Independence and Obligation. It should have concluded about 2/3rds of the way through book 18 because the story of The Crimson Vow was concluded because of the Avengers Assemble scene. But if you dont understand why Mile doesnt explain anything until book 17 is that Mile doesnt believe that Kurihara Misato was likeable and she is defined by her anxiety of her crippling fear of social isolation and its only being actually challenged on her web of lies that gets her accepted
